While it's sort of the same thing, I think it's much more a symptom of not enough compute vs some 'dump cheap tokens' on the market strategy.
One related thought I had was that given OpenAI is the only one _not_ doing this of the big3, it probably indicates they have a lot more spare compute.
It doesn't make sense to me that given the absolutely brutal competition any of these companies would block use of 3rd party apps unless they had to. They clearly have enough cash, so I don't think it's about money - I think it's that an indicator that Google and Anthropic are really struggling with keeping up with demand. Given Anthropics reliability issues last week this does not surprise me.
